The puzzle shelf 4 boxes on the shelf
Puzzle boxes,
for one sitting.
Stand-alone puzzle boxes — no series to follow, no characters to remember, just a deck of cards, a tricky lock and an evening to crack it. Solo or small groups. Posted worldwide.

Pick a puzzle
Each box is a single sitting — pull out the cards, divide them across the table, work in parallel, and meet in the middle with the answer. Experienced puzzlers tend to crack one in 60–90 minutes; newer puzzlers may want a long evening.

How a puzzle box works
A single sitting, a single answer.
Every box contains a deck of stand-alone puzzle cards. Each one can be solved on its own — pass them around, divide and conquer — but their answers feed into one final solution. Sealed solutions stay tucked away until you're ready to check your work. No companion website, no app, just paper and pencil.
